Pins: 07; pin pitch: 3.81mm; Angled; threaded flange; footprint includes mount hole for the setscrew (in mm). Larger values for the setscrew (in mm). If you don't need a noise and envelope generator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm?
